Hello,

I am trying to start above mentioned display. I tried to write initialization code based on documents of the display. No success. I also searched internet (including this forum), and tried to write code, based on programs I've found. No success.

I am using 89S8253 and 4-bit connection. Below is the code I am using. I get blank display with two lines (obviously not proper initialized lcd). Does anyone have any suggestion or working code (preferrably in C)?

thank you and a happy new year to everyone!

delay (1500); 

 // 4-bit, font 5x8, duty??? ram??
 lcd_code (0%11011010);  delay (1000);
 
 // SE: autoincrement on write, no inc. on read
 lcd_code (0%01010010); delay (10);		
 
 // display off, set cursor and underline mode off
 lcd_code (0x2F); delay (10);			
  
 // SU:
 lcd_code (0x01); delay (100);	// clear ram
 lcd_code (0x03); delay (10);	// cursor home, display start
 
 
 lcd_code (0x3F);// display on, set cursor and underline on
 delay (100);

 return;
